Hi Kingsley,

	That is really nice. What you have is a way to specify for your foaf  
file via a web interface which properties are visible to which of  
three selected groups: public, friends, private.  Is the  friends  
group you mention, the subset of your friends who have an account on  
ODS? Or does it extend to any friend you link to in your foaf file,  
whatever the domain of their URL?

What I am not clear about is how a Semantic Web client, such as  
Beatnik [1], can know that it needs to login using openid in order to  
get more information on a foaf file. I think this needs to be  
expressed in the foaf file too in a standard manner to make it machine  
readable.
